help with wiper wiring

[hotrodder]

I have rewired my 66 with a aftermark wiring kit. I cannot figure out how to power the wipers. the kit has a wiper power wire, but what wire does it attach to? I have the oem harness from the wiper motor to the switch. there is a yellow , blue, and I think brown might be black can't really tell which. the yellow wire and blue wire, are not attached to the plug that goes to the switch only the black(?) or brown it appears that one of the two was attached to the switch but has pulled out of the connector. any help on how to wire this? the truck has 2 speed wipers and washer pump, but the washers didn't work before the rewire.
Thanks

I had the same problem when i did my 71 t-37. If you read, a lot of the kits don't provide you any ground wires. The wiper motor gets power on with key on, and then the wiper switch is switching the GROUND connection to different posts. Let me find a diagram that might help:

BTW pretty sure C is the wiper power, d is power to washer solenoid, dark blue i think is ground to washer solenoid, F G and H are wipers three speeds.

That's if i recall reading this right.
